[thk70]

Virtual omv 4.1.12 on ESXi vSphere 6 Hypervisor Trying to enable the plugin "printing" but it errors when click "Save":

OMV 4.1.17-1 4.9 Linux no Hypervisor

Same issue for me

I looked at this but since I don't use it, I really don't know what is wrong. This plugin is going away in favor of docker. I think you would be better trying docker now.

Im curious what the preferred docker image is for replacing this feature.

[ryecoaaron]

I don't use cups but there are some images on docker hub that have 50K+ downloads - https://hub.docker.com/search?q=cups&type=image

@ryecoaaron thanks for the reply. I messed around with a few, but they either weren't compatible with ARM or they just didnt seem to work. I was able to get the desired AirPrint functionality using this tutorial. If I find some time I'll make a docker container and post it here. Suggest this issue is closed.

I have openmediavault-cups-3.1.2, for me the error was into the file /usr/sbin/omv-cups-avahi at lines 119 and 12:

    if not port_no:
        port_no = self.port

after comment these lines, cups start correctly.

I hope this helping someone.

This error seems to imply that the CUPS server is just not running. It happened to me after upgrading from OMV 3.x to 4x. I uninstalled the cups plugin first and re-installed, and tried the fix from @vpistis but it didn't help. I finally just ran sudo systemctl restart cups.service and voila! I was able to enable the OMV plugin and it recognized the printer I previously had set up.

Thanks mattcasey. You're systemctl command worked for me. I did not employ vpistis's suggestion, only yours, and I'm up and running now.

Hi, thanks to vpistis I managed to get my printer with my omv 4.1.35-1 visible in my network. I can print from localhost:631 test pages and via line command (with lp cups.conf for example). On my Windows 10 computer and on my Iphone the printer shows up but doesn't print. On the Windows 10 system there is an error message "Document could not be printed" and "An error occurred during printing". On the Iphone I can select the Airprint Printer correctly. When I start printing, a messege indicates that Iphone tries to connect to the printer, but nothing happens. On the localhost:631 page for admin the printer is listed. Features are: Idling, ready to take orders, no network release standard printer, colour management. I have tried several times as an admin to change to "network release active" but I failed. It simply doesn't change. Can anybody give me an advice where I can change this ???
